Metric DIN 127 Spring Lock Washer "B" Stainless Steel

DIN 127 Helical Spring Split Lock Washers are the most commonly used metric lock washers – It is a split metal ring that is bent into a helical shape. Split Lock Washers are a left hand helix and allow the nut to be tightened in a right hand direction only. When compressed by tightening the nut, the washer bites into the substrate and exerts a spring force between the bolt and the substrate creating frictional resistance to rotation. Available in high grade A1 stainless steel, marine grade A4 stainless steel and 316TI (A5) stainless steel (an even higher grade of corrosion resistance).
